To all whom it may concern:

Be it known that I, WILLIAM HENRY SUT- TON, a citizen of the United States of America, residing at Kinston, in the county of Lenoir and State of North Carolina, have invented new and useful Improvements in Marking Attachments for Plows, of which the following is a specification' This invention relates to marking attachments for plows, the object of the invention bein to provide a simple and effective marking device which may be thrown over to operate upon either side of the low for accurately gaging and marking o L the distance between rows.

The referred embodiment of the invention is i lustrated in the accompanying drawin s, in which-- igure 1 is a perspective view showing the application of the invention to a plow. Fig. 2 1s a perspective view of the supportingbracket and pivoted end of the marker-carrying and gage bar. Fig. 3 is a sectional view through the gage bar and slide.

Referring now more particularly to the drawings, the numeral 1 designates the beam of a plow, upon which is supported a bracketplate 2, said plate being arranged to rest upon the upper surface of the beam and extending transversely thereof and secured thereto by U-shaped bolts or clips 3. These bolts or cli s embrace the beam and have their threadbd terminals projecting upward through slots 4, formed in the late, and fitted. with clamping-nuts 5, the s ots 4 being of sufficient length to enable the plate to be adjusted to project equally beyond the sides of the beam. A bar 6 is pivotally connected at one end, as indicated at 7, to the center of the bracket-plate, so as to be swung over the beam to project laterally at either side thereof, the pivotal connection preferably being made through the medium of screw eyes or bolts, the screw eye or bolt upon the bar being carried by or passing through a U-shaped wear-plate 8, rotecting the pivoted en of the bar. The ar is adapted when swung in opposite directions to fit between opposite sets or pairs of stay-lugs 9 and 10, extending upwardly from the bracket-plate, and to there y be effectually stayed and supported in operative position. The inner faces of the stay-lugs are preferably flared or diverged in an upward direction, so as to enable the bar to be readily guided between them and to fit with sufficient friction to prevent its upward displacement under ordinary strain.

One of the faces of the bar 6 is provided with a gage 11, laid off in feet and inches, and car ried by the bar is a marker-holder 12,- slidably mounted on the bar, so that it may be adjusted to support the marking device atany desired distance from the beam, which may be accurately determined by adjusting the holder to register with a desired gage-mark. The holder 12 is adapted to be fixed in adjusted position upon the bar by a set-screw 13 and is provided with a vertical passage 14, receiving the supporting stem or member 15 of a marking device, whlch stem carries at its ends pivoted marking-fingers 16, the lower ends of which are adapted to form a line upon the surface of the ground at a desired distance from the shovel of the plow. The suporting-stem 15 is fixed in adjusted position a set-screw 17, carried by the slide-block 12,and maybe inserted orremoved upon slackening the set-screws by adjusting the fingers 16 to lie in the plane of the stem and sliding the marker as a whole in one direction or the other through the passage 14, as will be readily understood. The pivoted fingers 16 are adapted to ride over clods and other obstructions without injury and are adapted to swing by gravity to operative position when the bar 6 is swung to either side of the plow. The marking device is movable endwise in the passage 14, so that the jointed ends of the fingers may be drawn into the passage to lock the acting finger against pivotal movement. One or the other of the fingers will be in position for operation when the bar is swung to one side or the other of this beam, while the inactive finger will swing to a horizontal position, so as to avoid interfering projection.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the device will be readily understood, and it will be seen that a marking attachment is provided which may be readily applied to any plow and used to accurately mark the distance between rows on either the landside or shareside of the plow.

Having thus described the invention, what is claimed as new is A marking attachment for lows comprising a bracket having means 0 attachment to a plow-beam, a bar pivotally connected with the bracket to be swung to project beyond either side of the beam, means for staying the marking-finger into the passage to make said bar in either of its operative positions, a finger r1 id with the holder, and means upon holder slidably mounted upon the bar and the hol er for fastening the stem thereto, having a vertical passage, means for seeursubstantially as described.
